UI was sending GSM900 but backend REGIONAL_BANDS expects EGSM900
for Europe and Asia regions, causing validation rejection.

GSM Spy was failing with FileNotFoundError because grgsm_scanner
wasn't installed. These tools are now installed automatically by
setup.sh (both Debian and macOS) and included in the Dockerfile,
matching how other tools like multimon-ng and ffmpeg are handled.
- setup.sh: Remove ask_yes_no prompts for gr-gsm and tshark, install
unconditionally; add check_recommended tier for final summary
- Dockerfile: Add tshark to apt layer, add gr-gsm RUN layer with
apt-then-source-build fallback, preseed debconf for tshark
- gsm_spy.py: Add shutil.which pre-check in start_scanner route,
catch FileNotFoundError in scanner_thread to stop retry loop

- kill_all() now resets gsm_spy_scanner_running and related state so
the scanner thread stops after killall
- scanner_thread sets flag to False instead of None on exit
- Restore alert_rules, alert_events, recording_sessions tables and
wifi_clients column removed by PR in database.py
- Escape all server-sourced values in analysis modals with escapeHtml()
- Reset gsm_towers_found/gsm_devices_tracked on stop to prevent
counter drift across sessions
- Replace raw terminate/kill with safe_terminate() in scanner_thread

The function-strip CSS was never linked in index.html, causing all

Move waterfall controls from the sidebar into a function-strip bar inside
#listeningPostVisuals so they sit directly above the waterfall canvas.
Also fix the "SDR device in use" error when clicking a waterfall frequency
to listen — the WebSocket waterfall's device claim wasn't being released
before the audio start request because the backend cleanup hadn't finished.

Zooming caused "I/Q capture process exited immediately" because the client
closed the WebSocket and opened a new one, racing with the old rtl_sdr
process releasing the USB device. Now zoom/retune sends a start command on
the existing WebSocket, and the server adds a USB release delay plus retry
loop when restarting capture within the same connection.

The FFT pipeline produces power values in the ~0-60 dB range for
normalized IQ data, but quantize_to_uint8 used a hardcoded range
of -90 to -20 dB. Every bin saturated to 255, producing a uniform
yellow waterfall with no signal differentiation.
Now auto-scales to the actual min/max of each frame so the full
colour palette is always used.

After a WebSocket handler exits, flask-sock returns a Response to
Werkzeug which writes "HTTP/1.1 200 OK..." on the still-open socket.
Browsers see these HTTP bytes as a malformed WebSocket frame, causing
"Invalid frame header".
Now the handler explicitly closes the raw TCP socket after the
WebSocket close handshake, so Werkzeug's write harmlessly fails.
Applied to both waterfall and audio WebSocket handlers.

simple-websocket 1.1.0's receive(timeout=N) returns None on timeout
instead of raising TimeoutError. The handler treated None as
"connection closed" and broke out of the loop, causing Werkzeug to
write its HTTP 200 response on the still-open WebSocket socket.
The browser saw those HTTP bytes as an invalid WebSocket frame.
Now checks ws.connected to distinguish timeout (None + connected)
from actual close (None + not connected).

agents.js syncLocalModeStates() expects these endpoints to check
whether each mode is running locally. Both were missing, causing

The before_request require_login hook was returning a 302 redirect
for WebSocket upgrade requests, which browsers report as "Invalid
frame header". WebSocket requests don't always carry session cookies
reliably. Allow /ws/ paths through the login check since the page
that initiates these connections already requires authentication.
Also keeps the prior fix: serialize WebSocket sends through a queue
to avoid concurrent read/write on the non-thread-safe simple-websocket.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The fft_reader thread was calling ws.send() concurrently with
ws.receive() in the main loop. simple-websocket is not thread-safe
for simultaneous read/write, corrupting frame headers. Now the reader
thread enqueues frames and only the main loop touches the WebSocket.

Replace the batch rtl_power SSE pipeline with continuous I/Q streaming
via WebSocket for smooth ~25fps waterfall display. The server captures
raw I/Q samples (rtl_sdr/rx_sdr), computes Hann-windowed FFT, and
sends compact binary frames (1035 bytes vs ~15KB JSON, 93% reduction).
Client falls back to existing SSE path if WebSocket is unavailable.

Waterfall clicks now auto-select the correct modulation for the frequency
band (e.g., WFM for FM broadcast, AM for airband) instead of using whatever
modulation was last selected. Adds a hover tooltip showing frequency and
suggested modulation. Fixes the kill-all notification to show a clean
"All processes stopped" message instead of listing "bluetooth_scanner".

Enable -M level on rtl_433 to include RSSI/SNR in decoded JSON, extract

Tap the rtl_fm → multimon-ng audio pipeline via a relay thread to extract

Reverts IQ pipeline and removes syncWaterfallToFrequency calls from
pager, sensor, rtlamr, DMR, SSTV, and SSTV general modes. Waterfall

Replace rtl_fm/rtl_433 with rtl_sdr for raw IQ capture when available,
enabling a Python IQ processor to compute FFT for the waterfall while
simultaneously feeding decoded data to multimon-ng (pager) or rtl_433
(sensor). Falls back to the legacy pipeline when rtl_sdr is unavailable.

- Kill audio pipeline when startup produces no data instead of leaving
zombie processes running
- Skip unnecessary 1s USB release delay when no processes were active
- Remove racy fresh=1 pipeline restart from stream endpoint

Stream threads for sensor, pager, acars, rtlamr, dmr, and dsc modes
never called release_sdr_device() when their SDR process crashed,
leaving devices permanently locked in the registry. Also fixes orphaned
companion processes (rtl_fm, rtl_tcp) not being killed on crash, start
path failures leaking processes, DMR stop handler missing lock, and
listening post/audio websocket pkill nuking all system-wide rtl_fm
processes. Wires up register_process()/unregister_process() so the
atexit/signal cleanup safety net actually works, and adds rtl_tcp,
rtl_power, rtlamr, ffmpeg to the killall endpoint.

Fix infinite CPU spin in PD120 decoding caused by a 1-sample rounding
mismatch between line_samples (24407) and the sum of sub-component
samples (24408). The feed() while loop would re-enter _decode_line()
endlessly when the buffer was too short by 1 sample. Added a stall
guard that breaks the loop when no progress is made.
Fix false "leader tone detected" in the signal monitor by requiring
the detected tone to dominate the other tone by 2x, matching the
approach already used by the VIS detector.

When the WiFi interface is down (e.g. USB adapter not activated),
scanning fails with "Network is down" errors. Now the scanner
proactively checks interface state via /sys/class/net and brings
it up using ip link (or ifconfig fallback) before attempting scans,
with a retry loop if the initial scan still fails.

The Receiver Count section had no <h3> so it didn't get collapsible

Static minZoom: 2 wasn't enough for tall containers. Now calculate
minZoom from actual container height so tiles always cover the visible
area. Also set map background to match CartoDB dark tile ocean color
so any remaining edge at extreme latitudes blends seamlessly.

The dmrRawOutput div was rendering garbled box-drawing characters from
the dsd-fme ASCII art banner below the signal activity canvas. Remove
the div and filter banner lines (box-drawing chars, version info) in
the parser so they never become events.

The stream thread used a blocking readline() with no timeout, so once
DSD finished outputting its startup banner there were no more events
until actual signal activity. The frontend decayed to zero and appeared
dead. If DSD crashed, the synthesizer state never transitioned to
'stopped' so there was no visual or textual indication of failure.
- Use select() with 1s timeout on DSD stderr to avoid indefinite block
- Send heartbeat events every 3s while decoder is alive but idle
- Detect DSD crashes: capture exit code and remaining stderr, send as
'crashed' status with details and show notification to user
- Frontend properly transitions synthesizer to 'stopped' on process
death (was only happening on user-initiated stop)
- Increase idle breathing amplitude so LISTENING state is clearly
visible (0.12 +/- 0.06 vs old 0.05 +/- 0.035)
- Release device reservation on crash, not just user stop

DMR was missing checkDeviceAvailability/reserveDevice/releaseDevice
calls that other modes (SSTV, listening post) use, so the device
dropdown showed device 0 as available even when another process held
it. Also detect USB claim errors from rtl_fm and surface a clear
message telling the user to pick a different device.

The DSD stderr parser had regex ordering bugs that swallowed voice and
call events as bare slot events, and only matched classic dsd output
format (not dsd-fme). Unmatched lines were silently dropped, leaving
the signal activity panel with nothing to display.
- Reorder regex checks: TG/Src before voice before slot
- Support dsd-fme comma-separated format (TG: x, Src: y)
- Make bare slot regex strict (only standalone "Slot N" lines)
- Forward unmatched DSD lines as raw events for diagnostics
- Add LISTENING state to signal activity panel for raw output
- Show raw decoder output text below synthesizer canvas
- Fix test mocks for find_dsd() tuple return value

The APRS route called app_module.reserve_sdr_device() which does not
exist, causing an AttributeError that Flask returned as an HTML error
page. The frontend then failed to parse it as JSON, showing
"Unexpected token '<'" to the user. Fixed to use claim_sdr_device()
which is the correct function used by all other modes.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
SSTV was not claiming/releasing SDR devices through the centralized
registry, so the device state panel always showed the device as idle
during SSTV use. Added claim_sdr_device/release_sdr_device on the
backend and reserveDevice/releaseDevice on the frontend, matching the
pattern used by all other modes.

The decode canvas was always black because nothing drew on it. Now the
backend encodes partial JPEG snapshots every 5% progress and the frontend
